One was I discovered that as well as being fantastic for posting to del.icio.us, it also gives me access to all my del.icio.us bookmarks, organised by tag! By adding this to the Mac status bar at the top of the screen it gives me quick access to my del.icio.us bookmarks.
The other was reading the post in Justin Miller’s blog (the creator of Pukka) about “The Price of Free” which discusses the reluctance of people to pay for utility programs. Pukka was discussed favourably on a podcast, but the announcer was saying it should be free, not shareware.
I realised that $14.95USD (which was $16.27AUD) was a reasonable price for the time Pukka will save me and it will encourage me to make better use of del.icio.us. And hopefully paying for it will encourage Justin and others like him to keep providing great applications.
